IndicatorResult |
calculate(int startIndex,
int endIndex)
Calculates values of the indicator from startIndex to endIndex of input parameter and places them in output parameters
|
Point |
drawOutput(Graphics g,
int outputIdx,
Object values,
Color color,
Stroke stroke,
IIndicatorDrawingSupport indicatorDrawingSupport,
List<Shape> shapes,
Map<Color,List<Point>> handles)
This method will be called once for every output marked as drawnByIndicator every time the chart surface needs to be redrawn
|

getIndicatorInfo()
Returns object that describes indicator, how many inputs, outputs it has, where it should be shown etc
|
InputParameterInfo |
getInputParameterInfo(int index)
Returns object that describes one of the inputs
|
int |
getLookback()
Returns number of elements needed to calculate value of the first element.
|
int |
getLookforward()
Returns number of elements after last element needed to calculate value of the last element.

startIndex
- index of the first element in input parameters that needs corresponding indicator value. That doesn't mean that values
before startIndex will not be read, they will be if lookback is more than 0. That also doesn't mean that value for startIndex will be
calculated, it will be not if startIndex < lookback. IndicatorResult.getFirstValueIndex()
returns index of the first element that
has corresponding calculated value in output array(s)endIndex
- index of the last element in input parameters that needs corresponding indicator valuepublic IndicatorInfo getIndicatorInfo()
